Fix "Wayland's wl_display_dispatch() can block a Vulkan application" (#1354)

This rewriting of the FLTK callback function that runs when there are data available
for reading in the socket connecting the app and the Wayland compositor is meant to
facilitate the integration of Vulkan.
This rewriting reproduces the recommended code to read from the socket
documented in Wayland function wl_display_prepare_read_queue() when several threads
potentially read from the socket.
